Judges 20:36-39

³⁶And the children of Benjamin saw that they were smitten; and the men of Israel gave place to Benjamin, because they trusted in the ambuscade which they had prepared against Gibeah.

³⁷And when they retreated, then the liers in wait rose up, and they moved on toward Gibeah, and the whole ambush came forth, and they smote the city with the edge of the sword.

³⁸And the children of Israel had a signal of battle with the liers in wait, that they should send up a signal of smoke from the city.

³⁹And the children of Israel saw that the liers in wait had seized Gibeah, and they stood in line of battle; and Benjamin began to smite down wounded ones among the men of Israel about thirty men; for they said, Surely they fall again before us, as in the first battle.
